Definitions

  • the present invention relates to an improvement of a fueling-error prevention device which is provided in an inside of a fuel flow path between a fueling opening and a fuel tank; blocks the fueling by a fueling nozzle when the fueling nozzle having a diameter less than a predetermined diameter is inserted in the fuel flow path; and allows the fueling by the fueling nozzle when the fueling nozzle having the predetermined diameter is inserted in the fuel flow path.
  • Patent Document 1 There is a device shown in Patent Document 1, which prevents the fueling of non-predetermined types of fuels by the fueling nozzle which does not reach the predetermined diameter, i.e., a fueling error, with a mechanical structure.
  • a flap which becomes a valve body is rotatably attached to one of a pair of reception means which can be pressed apart outwardly, and in a state before a pair of the reception means is pressed apart, a free end of the flap is engaged with the other of a pair of the reception means so as to block a rotation of the flap in a valve-opened position.
  • Patent Document 2 discloses a fueling error prevention device adapted to be provided inside a fuel flow part between a fueling opening and a fuel tank, comprising a flap valve provided on one of first and second radial moveable elements, wherein by moving one of the two elements in a separating direction by an abutment of a fueling nozzle against one element by inserting the fueling nozzle having a predetermined diameter, the other one of the two elements is moved in the separating direction.
  • the flap valve is operable by a movement of the other element in the separating direction by the abutment of the fueling nozzle.
  • Patent Documents 3 to 6 describe fueling error prevention devices in accordance with the technical background of the invention.
  • Patent document 2 describes a fueling-error prevention device adapted to be provided inside a fuel flow path between a fueling opening and a fuel tank, comprising:
  • the main feature to be solved by the present invention is to provide a device which can reliably prevent the fueling error with the mechanical structure.
  • the fueling-error prevention device is provided inside of the fuel flow path between the fueling opening and the fuel tank.
  • the fueling-error prevention device comprises the flap valve positioned in a valve-closed position blocking the fuel flow path by urging to block the fueling nozzle from proceeding; the first slider supporting the flap valve openably and closably, and also supported slidably and movably in a direction crossing an axis line of the fuel flow path; the second slider comprising an engaging portion relative to the flap valve which is in the valve-closed position, and also supported slidably and movably in the direction crossing the axis line of the fuel flow path; an urging device urging the first slider and the second slider in an approaching direction; and a lock member blocking one of either the first slider or the second slider from moving in the separating direction against the urging of the urging device.
  • the blocking of the movement by the lock member is released by the movement of the other of the first slider or the second slider which moves against the urging of the urging device by the abutment of the fueling nozzle having the predetermined diameter accompanied by the insertion of the fueling nozzle having the predetermined diameter.
  • the aforementioned release allows one of the first slider or the second slider to move against the urging of the urging device due to the abutment of the fueling nozzle. Due to the movement of one slider, an engagement of the other one slider relative to the flap valve is released.
  • lock member is supported slidably and movably between a lock position blocking one of either the first slider or the second slider from moving in the separating direction, and a non-lock position, and also that the lock member is recoiled and urged toward the lock position.
  • lock member includes an abutting portion relative to a back portion of one of either the first slider or the second slider, and moves up to the non-lock position in a direction along the axis line of the fuel flow path against the urging to release the abutment of the abutting portion relative to the back portion.
  • a movement to a valve-opened position of the flap valve closing the fuel flow path openably is allowed for the first time by the movement of one of the first or the second sliders which becomes movable as a trigger of the movement of the other of the first or the second sliders. Accordingly, in addition to the movement of the other of the first or the second sliders, as long as a fueling nozzle having a thickness allowing one of the first or the second sliders to move for a predetermined distance, i.e., the fueling nozzle having the predetermined diameter is not inserted into the fuel flow path, the flap valve never moves to the valve-opened position. For example, even if the fueling nozzle which does not reach the predetermined diameter is inserted into the fuel flow path, and is operated to sway inside the fuel flow path, only the other of the first or the second sliders moves, and the flap valve is never opened.
  • the fueling of the non-predetermined types of fuels by the fueling nozzle which does not reach the predetermined diameter, i.e., the fueling error, can be reliably prevented.
  • a fueling-error prevention device is provided in an inside of a fuel flow path L between a fueling opening H and a fuel tank; blocks the fueling by a fueling nozzle N" having a diameter less than a predetermined diameter when the fueling nozzle N" having the diameter less than the predetermined diameter is inserted in the fuel flow path L; and allows the fueling by a fueling nozzle N' having the predetermined diameter when the fueling nozzle N' having the predetermined diameter is inserted in the fuel flow path L.
  • such prevention device opens the later-mentioned flap valve 1, and allows an insertion of the fueling nozzle further than the flap valve 1 to allow a fueling thereof.
  • the fueling nozzle of the fueling gun which fuels a gasoline fuel and has a diameter smaller than that of the fueling nozzle of the fueling gun which fuels the diesel fuel from the fueling opening H
  • such prevention device maintains a valve-closed state of the later-mentioned flap valve 1, and blocks the insertion of the fueling nozzle further than the flap valve 1 to be incapable of the fueling thereof.
